This invention relates to agitating disks for washing machines. V

One of the objects of the invention is in the provision of an agitating disk for washing machines, the same being of simple construction and adapted, due to its peculiar fashioning, to exert an increased rubbing effect upon the clothes content.

Another object thereof is in the provision of an agitating disk for washing machines fashioned in a manner'to be floated, due to the agitating movement thereof, said disk having an increasedrubbing effect upon the clothes content, due to a double edged fash- 5 ioning of the lower portions of the ribs on the disk. 1 i

A further object isin the provision of an agitating disk including a plurality of rib members uponthe lower face thereof, said rib members having their lower edges fashioned in a manner to increase the rubbing effect upon the clothes content,

A still further object is in the provision of an agitating disk, including a plurality of i rib members, said rib members having their clothes contacting portions fashioned in a double edged manner, there being provided a Web between the edges to provide a channel wherein the speed of the water action is increased in a manner to protect the clothes content during the rubbing action, and pre vent the clothes being drawn into the perforations in the pocket of the disk by the upward suction of the disk during agitation.

Other objects of the invention will appear in the following specification, taken in c0nnection with the annexed drawings, in Which-- Fig. 1 is an elevation, showing a washing machine with portions thereof cut away for a more detailed disclosure of the agitating disk and 'drive means therefor;

Fig. 2 is a cross-sectional view of the agitating disk; and

Fig. 3 is a plan view, from below, of the disk.

Referring to the drawings, there is shown in Fig. 1 a general view of a washing machine, utilizing an agitating disk of the type mechanism.

ppnsl il lltillg the basis for the present applica- 1011.

The washing machine here shown has been selected merely for the purposes of a general showing of the driving means for the agitator, and it is obvious thatany type of washing machine utilizing an agitating disk might similarly be used. 1 r

The present disk is an improvement upon a hydro-disk for washing machines, described and claimed in a pending application filed by one John Nelson, December 28,

1923, and bearing Serial Number 683,123. 1

Referring to Fig. 1, wherein a general View of a washing machine with the agitating disk applied thereto is shown, we find the conven- .tional tub portion 10 and framing 11. Suitably mounted upon the frame portion is an electric motor which provides the power means for the driving mechanism for the agitating disk, the same including generally the pulley 13 and a series of gears generally referred to as 14:, which provide the driving means for the vertically disposed drive shaft 15. A segmental rack 16 is moved in a reciprocatory manner by the drive shaft 15, said rack actuating a gear 17 located upon the upper side of the washing machine. Slidably connected with said gear 17 is the rod 18 which completes the driving connection for the agitating disk, which is fixedly attached to the lower end thereof. The rod 18, previously mentioned, is slidably related to the driving gear 17 and permits raising and lowering of the disk member.

Referring specifically to the agitating disk, which forms the basis for the present application, it has been explained before' that this disk is an improvement over a former disk, the same appearing in the before-mentioned application. The agitating disk comprises a plate 19, the same having a hub portion 20 therein, in which is seated the lower end of the rod 18.

The plate 19 is fashioned in such manner that a plurality of ribs 21 project downwardly therefrom, comprising the water agitating The ribs 21 extend radially from points adjacent the center of the plate,

the side walls 22 thereof being flared upwardly, and the thickness of the ribs increasing gradually towards the outer edges thereof, which lie adjacent the periphery of the plate 19. By changing the angle of the side walls, variation in the buoyancy of the disk is effected. The ribs, as a matter of fact, are fashioned from the plate 19 itself, with the result that pockets 23 are formed in said plate. The outer ends of the pockets 23 are substantially closed, as indicated at 24. The ribs are fashioned upon their lower side with two relativel spaced rubbing edge members 25, connected by a perforated web 26, above the edges of the said rubbing members and extendin in an outward and downward direction rom points adjacent the center of the disk.

Referring specially to the formation of the rib members 21, it is mentioned that the width of said rib members, as distinguished from a thin rib, serves to protect the clothes content that is being washed. However, in fashioning the rib with the rubbing members, the efliciency over the ordinary single rib is doubled, and at the same time the clothing is protected.

By providing the narrow depressed channelway 27 in the rib, a water bridge is formed, which acts as a supplemental bearing or impin ement surface in conjunction with the rub ing members 25.

When the disk is reciprocated, lateral deflection of the water results, both between the separate ribs, and also between the rubbing members of each rib, the deflection in the latter being accelerated over that of the former (between the ribs) because of the narrowness and shallowness of the channelways, which exerts a constant releasing tendency of the rubbin members from contact with the clothing. ause of the multiplicity of edges 25, the rubbing and agitating eflect upon the clothing content positively prevents entanglement with the edges of the rib. The perforations in the web 26 merely serve to afford water passage or drain through the disk. However, by extending the rubbing edges between the perforations, the drawing of the clothes into the perforations by the upward suction of the disk is prevented.

The operation of the present disk is similar to that disclosed in the above mentioned copending application, wherein the fashioning of the disk is such that the agitating effect thereof with the water in the tub results in the raising of the disk to a floating position upon the surface of the water, this position being the normal operating position of the disk with respect to the clothes content during the washing operation.

The improvement of the present disk lies in the increased efficiency in the washing operation, due to the particular fashioning of the rib members in the double edged manner with the narrow water channel therebetween.

By the above described fashioning of this heavier than water agitating disk, there is attained not only the speed of the washing operation, which is accomplished by the use of a narrow rib, but, more, an increased speed of washing action, due to the multiplying or the sharp rubbing elements with a combined resultant improvement in that the speed of the water in the narrower channel therebetween prevents tearing of the clothes content, which normally attends the vigorous abrasion action of a single rib upon the clothes.

What I claim is 1. An agitating disk having radially extending ribs upon its lower face, each rib having downwardly converging side walls, and a bottom portion comprising spaced rubbing edges and a perforated web therebetween.

2. An agitating disk having radially extending rib members upon its lower face, each rib member having downwardly extending converging side walls and a bottom portion including spaced rubbing edges and a perforated web therebetween.

3. An agitating disk having radially extending rib members upon its lower face, each rib having downwardly extending converging side walls increasing in width towards the periphery of the disk and a bottom por tion including spaced rubbing edges forming a narrow water channel therebetween.

4. An agitating disk having radially extending blades upon its lower face, said blades being of substantial side facial area providing for violent water agitation, said blades being provided at their lower edges with relatively spaced rib members, forming a water channel, and a perforated web therebetween.

5. In a device of the class described, in combination, a disk member, radially extending blades depending therefrom, said blade members being composed of side faces of substantial area and tapered in a manner to provide not only a violent water action but also movement of the disk to an elevated position, and a water channel formed between the edges of said dependingtapered blade portions.

In testimony whereof, I have hereunto affixed my signature.
